I believe for this shape, the formula is L•W•H divided by 3. So 13 would be L and W. 18 would be H, so all this together 13•13•18 divided by 3 should give u the answer.
We would have two circles of 5cm diameter each, and a rectangle of the length pi*diameter and 2cm, so lets add them:
total = 2circles + rectangle
total = 2(2*pi*(5/2)^2) + pi*diameter*heigth
= 4*pi*(2.5)^2 + pi*5*2
= 109.9
that is the surface area of a bar soap 109.9 cm^2
Answer: To find the surface area of a prism (or any other geometric solid) we open the solid like a carton box and flatten it out to find all included geometric forms. To find the volume of a prism (it doesn't matter if it is rectangular or triangular) we multiply the area of the base, called the base area B, by the height h.
The right answer for the question that is being asked and shown above is that: "log2(4x) = log2 (4) + log2 (x)." The equation that illustrates the product rule for logarithmic equations is that <span>log2(4x) = log2 (4) + log2 (x)</span>
